“…Note that egg albumen is composed of various proteins [33]. Conduction characteristics could be related to oxygen ions originating from the oxygen-containing functional groups in hydroxyl and carboxyl proteins [31,32]. Oxygen ions are randomly distributed in the albumen layer prior to applying a voltage bias to the Al/ Albumen/ITO device.…”

“…Natural biomaterials are particularly promising due to their biodegradable, biocompatible, solution-processable, cost-effective, and eco-friendly nature [27,28]. Egg albumen, as a naturally abundant material, has been employed as ideal active media in high-performance RS devices [29][30][31]. Most devices employing albumen as the RS layers exhibit bipolar switching [32][33][34].…”

The concept of complementary resistive switching (CRS) has been proposed as a potential solution for mitigating the unwanted sneak path current intrinsic to large-scale crossbar memory arrays. In this study, CRS devices based on egg albumen are fabricated using non-inert Al layers as the top electrodes (TE). The Al/Albumen/indium tin oxide (ITO) single sandwich structure achieves stable and reproducible CRS behavior without requiring a forming process. The application of a compliance current leads to an evolution from CRS to bipolar resistive switching (BRS). Furthermore, the BRS analog switching feature enables the emulation of synaptic functions, like paired-pulse facilitation (PPF) and paired-pulse depression (PPD). Our systematic and in-depth analyses demonstrate that the CRS is due to the interfacial Schottky barriers originating from the Al electrode oxidation. Consequently, the resistance switching behavior in the albumen-based cells with inert Pt top electrodes can further validate this model. These findings provide significant insight into the role of non-inert electrodes and contribute to a comprehensive understanding of the CRS mechanism, which may facilitate the development of high-performance CRS biodevices.

Artificial synaptic devices are the essential hardware component in emerging neuromorphic computing systems by mimicking biological synapse and brain functions. When made from natural organic materials such as protein and carbohydrate, they have potential to improve sustainability and reduce electronic waste by enabling environmentally‐friendly disposal. In this paper, a new natural organic memristor based artificial synaptic device is reported with the memristive film processed by a honey and carbon nanotube (CNT) admixture, that is, honey‐CNT memristor. Optical microscopy, scanning electron microscopy, and micro‐Raman spectroscopy are employed to analyze the morphology and chemical structure of the honey‐CNT film. The device demonstrates analog memristive potentiation and depression, with the mechanism governing these functions explained by the formation and dissolution of conductive paths due to the electrochemical metal filaments which are assisted by CNT clusters and bundles in the honey‐CNT film. The honey‐CNT memristor successfully emulates synaptic functionalities such as short‐term plasticity and its transition to long‐term plasticity for memory rehearsal, spatial summation, and shunting inhibition, and for the first time, the classical conditioning behavior for associative learning by mimicking the Pavlov's dog experiment. All these results testify that honey‐CNT memristor based artificial synaptic device is promising for energy‐efficient and eco‐friendly neuromorphic systems.

In this paper, natural organic honey embedded with carbon nanotubes (CNTs) was studied as a resistive switching material for biodegradable nonvolatile memory in emerging neuromorphic systems. CNTs were dispersed in a honey-water solution with the concentration of 0.2 wt% CNT and 30 wt% honey. The final honey-CNT-water mixture was spin-coated and dried into a thin film sandwiched in between Cu bottom electrode and Al top electrode to form a honey-CNT based resistive switching memory (RSM). Surface morphology, electrical characteristics and current conduction mechanism were investigated. The results show that although CNTs formed agglomerations in the dried honey-CNT film, both switching speed and the stability in SET and RESET process of honey-CNT RSM were improved. The mechanism of current conduction in CNT is governed by Ohm’s law in low-resistance state and the low-voltage range in high-resistance state, but transits to the space charge limited conduction at high voltages approaching the SET voltage.
